Application liled March l2, 1900. Serial No. 8,343 ililo model-l To r/Z7071/071?, 'it 77cm/ concern,.-

Be it known that I, WILBER J. PINE, a citizen of the United States,residing at Oshkosh, in the county of l/Vinnebago and State ofViscousin, have invented a new and useful Improvement inFlushing-Valves, of which the following is a specilication.

The object of my invention is to provide a simple and efficient valvefor iiushing waterclosets or other places where iiushing is required;and the invention consists in the features and combinations hereinafterdescribed and claimed.

In the accompanying drawings, Figure l is a sectional elevation of myimproved flushing-valve; Fig. 2, an elevation, partly broken away,showing the upper disk open and the lower disk closed; Fig. 3, aperspective detail of the release and lock for the valve-stem, showingthe parts separated; Fig. 4, a crosssection taken on line 4 of Fig. llooking in the direction of the arrow; Fig. 5, a detail showing amodification in the support and lock for the same; Fig. 6, adetail inperspective of the parts shown in Fig. 5, separated; Fig. 7, a detailshowing a modification in the lock for the valve-stein; Fig. 8, a detailin perspective of the parts shown in Fig. '7; Fig. 9, a side elevationwith the shell or casing partly broken away, showing the parts inposition with the induction-passage open and showing a modification ofthe construction, arrangement, and location of the cushioningpiston-chamber; and Fig. lO, a sectional elevation of the lower portionof the valve, showing the construction of Fig. 9 with theinduction-passage closed and the relief-passage open from thelioat-chaniber.

In constructing my improved flushingvalve I provide a casting or shellA, having an inlet or induction passage A' and an outlet or ed notionpassage A2. The shell around each of the passages has a wall or rimscrewthreaded for the attachment of the valve to the supply andrilischarge pipes. The induction and eduction passages are separated bycushion to prevent the main disk from being closed too forcibly. Themain disk D, as shown, is formed of a metal portion d and a packing dl,the packing' seating against the edge of the opening a in the wall awhen the disk is closed. In the construction shown the main disk isscrew-threaded onto the valve-stem C, so as to be adjustable thereon forproperly seating the disk. The valvestem also carries a second disk E,oppositely faced to the main disk D, which disk, as shown, is alsoscrew-threaded onto the stem and is adjusted and held in position bynuts or otherwise. This second disk enters au opening e in the outerwall of the main shell and seats against a flange at the bottom of theopening, so as to close a port c', and, as shown, a guide and supportagainst lateral pressure on the valve-stem is furnished by an annular riin or wall c2, partially encircling the saine and against which thefaces of the adjusting and locking nuts bear in the movements of thevalve.

A cylinder or shell F is screw-threaded onto the outer wall of the mainshell or casing, forming a float Water-chamber for the admission ofWater thereinto when the main disk is open, such admission being througha port f in the wall of the main casing. The port fis regulated andcontrolled as to the amount of water passed, in the construction shown,by a valve j", entered through a screw-threaded hole in the main shellor casing, which valve, as shown, is nicked at its outer end for thereception of a screw-driver or other tool, by means of which the valvecan be advanced and receded to decrease or increase the size of theopening through the port ffor the passage of Water. The outer end of thevalve is encircled by a rim or wallfg, forming a packing-box for thereception of a suitable packing compressed by a screw-threaded plug f3,so as to always insure a tight joint around the Valve, which is ofcourse necessary to prevent leakage in adjusting the valve.

'Ihe float Water-chamber formed bythe casing F has located therein afloat G, which is loosely mounted on the valve-stein and free to riseand fallin the chamber. As shown in Figs. l to 3, the bottoni of thefloat has secured thereto slotted pendants 'or lugs g, through the slotsof which pass arm hof a lever II, forming one portion ofaknuckle-jointconnection. The lever H is pivoted to a standard H', extending up fromthe wall of the main shell or casing, and has pivoted thereto two linksh', one on each side, which links in turn are pivoted to a collar h2,secured around the valve-stem C. The lever H, with the links h andcollar h2, constitutes a knuckle-jointconncction and furnishesalook forthe valve-stem. The knuckle-joint connection should be free to breakupward with the upward movement of the iioat, which releases the lock,and for this reason the pivots of the link to the valve-stem and to thereleasing-lever and of the releasing-lever to its standard when the'stem is pushed inward to open the valve should be in line, orapproximately so, for the weight of the fioat when down to hold the stemand its disk against outward movement. rIhe limit of the throw of theknuckle-joint downward should not be sufficient to produce a lock by thepassing of the pivots beyond the dead-center that would not be releasedwith the upward movement of the fioat to act on the releasing-lever, andto regulate and control the downward movement of the knuckle-joint, andfrom it the downward movement of the float, an adjusting-screw vl isprovided, thatengages a stop t" on the lever H, limiting the point ofdescent or downward movement of the lever andlink 'movement in an upwarddirection when the fioat rises.

`The-shell or casing F has mounted on its end a lever I, arranged tocontact with the end of the valve-stem for moving such stem to open thedisk D and close the disk E, opening the main supply for liushingpurposes and closing the discharge from the float-chamber, and at thesame time allow the main supply to pass through the port finto thefloatchamber.

The operation is as follows: When itis desired to iiush the basin, thelever I is pressed down, forcing down the valve-stem to open the disk Dand close the disk E, which movement also carries the piston at the endof the stem downward. The Water-supply for iiushing purposes passes intothe induction-passage A' through the openings around the casing B andenters the eduction-passage through the opening or port a. This supplypasses out through the eduction-passage 'to the basin, and aproportionate quantity thereof, regulated by the valvef, passes throughthe port 6o fand rises in the float-chamber, causing the oat to rise.The upward movement of the float raises the lever H, releasing theknucklejoint connection, so that the pressure entering theinduction-passage strikes the bottom of the diskD, raises the disk,closes the opening a', and shuts o the supply to the eduction-passageand basin. The upward movement of the valve-stem lifts the disk E fromits seat, opening the port or passage e' for the water in the float-chamber to discharge therefrom through the port into the ed uction chamberand passage to flow out therethrough to the basin, thus relieving thefioat-chamber of'the water and bringing the parts into position for thenext operation of iushing, which operation is accomplished by againforcing down the val ve-stem to open and close the respective disks. Theupward movement of the valve-stem carries with it the piston B', andsuch piston is forced against the water in the chamber of the casing B,the water furnishing a cushion to prevent any jar or concussion from thereturn of the stem and seating ofthe disk and allowing the disk to closegradually and only as the water escapes from the chamber surrounding thepiston. As will be seen the main supply of water for flushing purposesalso furnishesmeans for automatically operating the parts to shut offthe supply through the medium of the float, and this automatic operationcan be regulated as desired by simply adjusting the valvef to admit moreor less water to the float-chamber, thereby regulating the period andthe amount of water for flushing.

The knuckle-joint connection forms a lock for holding the main disk openuntil the Hushingis completed, which is determined by the release of thelock with the rise of the float. This lock instead of being of theconstruction shown in Figs. l to 3 can be of any suitable form ofconstruction that will furnish a releasable lock by the rise of thefloat. A modied form of lock for this purpose is shown in Figs. 5 and 6,in which the lever H is forked and the float rests directly on the armsh of the fork. An eccentric or releasing cam J is mounted in the supportor standard H and has secured to its pivotj` arms which extend out andare connected with pendants 9'2 from the bottom of the iioat. The riseof the float lifts the arms j and rocks or oscillates-the eccentric toengage the trip end i2 of the lever H and lift the knuckle-joint, sothat it passes the center free to rise, as in the arrangement shown inFigs. l to 3.

Another form of lock connection is shown in Figs. 7 and 8. A pivotedlatch or catch K is mounted on the upright or standard H' and isarranged to engage an arm KQ secured to the valve-stem. Thelatch hassecured thereto arms la, which are connected with the bottom of the oatby links lo', so that with the upward movement of the oat the links andarms will turn the catch or latch K and disengage it from the arm K forthe pressure of the supply on the disk D to operate the parts and closethe disk D and open the disk E, as already described. It is to beunderstood that the tloat acts to resist the pressure of the main diskonly to the extent that its weight serves to hold the knuckle-jointconnection in line to prevent the upward movement of the valve stem anddisk to close the induc- IOO IIC

tion port or passage. lts office is to furnish a means by which thepressure of the Water entering the float-chamber through the port fandacting on the bottom of the ioat will cause the float to rise and breakthe lock of the knuckle-joint, permitting the pressure to act on thevalve-disk and close the induction port or passage. The float is notintended to open the valve against the pressure of water thereon, assuch opening is from the lever I when forced downward, pushing the stemC downward or inward to open the disk D. The ioat never acts and couldnot act to open 'the main disk, as its only office is to retain theknuckle-joint in lock when the ioat is down and to release theknuckle-joint from its lock as the float rises.

The cushioning-piston and its chamber 'for holding the main disk againsttoo-rapid return in closing instead of being located in the indnotion-passage of the main shell or casing could be otherwise located. Alocation for this chamber and its piston is shown in Figs. il and l0 ason the upper side of the main shell or casing and surrounded by thechamber of the iioat. ln this arrangementthe casing B is Jformed withthe body of the main shell or casing, so as to inclose the cushion orliquid-pressure chamber B2, in which is located the piston B, attachedto the reciprocat-ing stem.

The cushion-chamber has communication with the float-chamber by means ofa passage or port l), and in communication with the discharge-port c,which in the construction shown is located in the bottom of thecushion-cham ber, is a chamber or passage c,which communicates with adischarge-pipe c', leading out through the ednction-passage.

The operation, so far as cushioning effect is concerned, is preciselythe same as described for the same parts in the construction of Figs. land 2, except that the wat-er to supply the resistance comes from theHeat-chamber and passes through the opening or port l) into the cushionor pressure chamber and thence up around the edge of the piston to lieabove the piston and by its slow discharge hold the main disk againstrapid and quick closing. The piston or cushion chamber in theconstruction of Figs. 9 and lO is open at the top and closed by ascrew-threaded cap B3, through which the valve-stem passes. rlhisarrangement, it will be seen, leaves the induction-passage free fromobstruction and so that the in flow ol;'\vate1\vill11ot be checked, and,as shown, the induction portion A3 of the main casing is a separatepiece attached to the neck A" by means of a screw-threaded locking andretaining band a5.

The valve as a whole in either form of construction and arrangement isto be attached hereinbefore described, and its operation is in bothcases the same so far as concerns controlling the inlet and outlet ofthe water for flushing purposes.

The principal advantages of my invention are that it eliminates theordinary flushingtank, that it can be connected up to a directwater-pressure, that it is self-regulating as to the quantity of wateradmitted for flushing purposes after its first adjustment and use, andthat it is always certain and noiseless in operation.
